Return type: OMX
Returns:       

The square root of either a floating point number or BCD number.

  define external float function
      sqrt value float x

  define external bcd function
      sqrt value bcd x

Use sqrt to calculate the square root of either

• a floating point number
• a BCD number

You must import either omfloat.xmd or ombcd.xmd in your program. Decide whether you want BCD mathematics (excellent for financial calculations) or floating point mathematics (excellent for extremely large numbers).

Floating Point Example:

  ; Displays the square root of 144 as a floating point number.
  import "omfloat.xmd" unprefixed
  process
    local float x initial {"144"}
    local float result

    set result to sqrt x
    output "result = " || "d" % result || "%n" 

BCD Example:

  ; Displays the square root of 144 as a BCD number.
  import "ombcd.xmd" unprefixed
  process
    local bcd x initial {"144"}
    local bcd result
    local bcd rounded-result

    set result to sqrt x
    set rounded-result to round result bankers-nearest 0.01
    output "The square root of " || "d" % x || " = " || "d" % rounded-result || "%n"
  ; Output: "The square root of 144 = 12"

If you take the square root of an integer, you need to coerce the integer - to a floating point or BCD number - so that the appropriate function is called. The result will depend on which square root function is called.

In an OmniMark program, always surround operators with spaces.
